Here it is:

And it's bad that this is able to make plasma hang. In the days of
cooperative multitasking, every application could make your system hang -
these days are over. But for plasma, it's still like this. And it's
happened really often to me. Installing custom plasmoids often is no fun.
So I stopped doing this, and things are better now :)
